在IntelliJ中调试scala sbt集成测试

Question

我使用IntelliJ的SBT插件，并创建了一个具有以下构建设置的scala项目：build.scala：

lazy val root =
    Project("root", file("."))
      .configs( IntegrationTest )
      .settings( Defaults.itSettings : _*)

<setting some parameters>
libraryDependencies += "org.scalatest" % "scala-test_2.10" % "1.0.8" % "test,it"

Unable to load a Suite class. This could be due to an error in your runpath. Missing class: it.AddPersonSpec
java.lang.ClassNotFoundException: it.AddPersonSpec

任何想法都是高度赞赏的。

Answer 1

在IntelliJ中，右键单击项目，转到Open Module Settings，选择Paths选项卡，并将Test output Path从.../target/scala-2.11/test-classes更改为.../target/scala-2.11/it-classes。这样，您就可以像正常测试一样调试集成测试。

在调试普通测试之前，必须将其改回。此外，将sbt项目导入IntelliJ将再次擦除该设置。
